Erroneous link between R/3 Schedule Lines and CRM Schedule Line

Question

Hi everybody,
I am analyzing the best approach to fix a duplicate schedule line issue in CRM. The documents are modified from R/3 by means of an IDOC (ORDERS05).
First of all, let me explain the process.
1.- Document is first created in CRM
2.- Document is updated from CRM in R/3 (Using middleware)
3.- In R/3, a customer program (Z), does a lot of calculations to the order (rejection, item splitting, Qty changes, creation of new Items, etc) and once its done, it populates the IDOC and sends the information to CRM (ORDERS05).
4.- CRM receives the IDOC, modifies the order.
5.- Document is update from CRM in R/3 9Using middleware)
The Z program, DOES NOT modify the database in R/3, it lets the process to be executed and also lets CRM to do this job.
I had to make several modifications to the XIF module, in order to allow many of those changes to be valid in CRM (i.e., A rejected ITEM is changed to be valid and it's Qty changed. CRM does not allow this to be done in one step, since the qty is "greyed" for no changes).

Answer 1

My issue is this.
The worst thing that happened, is the fact there is key fields in R/3 -> CRM, to link the schedule lines, since R/3 Uses the regular key fields in the T. table, CRM uses the GUID for the sched. lines.
After a OSS msg and many goes and comes, I had the suggestion from SAP to change from ORDERS05 Idoc into CRMXIF_ORDER_SAVE_M01 idoc, since ORDERS05 is not supported by CRM (however the Idoc is in the system).
I am not sure that is the best solution, in fact I do not believe that is a solution at all. CRMXIF_ORDER_SAVE_M01 does not exist in R/3 and even if somehow I do all the effort to create it in R/3, R/3 still does not have the schedule line GUID to properly point to the right record.
What I did to override this error, was to include inside the XIF module the CRM_APO_SALES_SELECT_GUIDS, CRM_ORDER_READ and CRM_ORDER_CONVERT_DOCNUMBER Functions to get all the sched lines for the specific orders in the guid form. However this solution does not work OK, since sometimes the CRM system is not able to properly return the correct GUID values and this leads to the duplicate schedule lines error.
If somebody has ever deal with a situation like this, I will appreciate if could share its point of view or even better, share the solution used.
As an extra comment, modifying the Z program to update the database and let middleware to do the job for us, is ou of the qustion at this momento.
Thank you for your time and help.
